Hi guys,

I'm trying to install Mountain Lion on my new Sony Vaio Laptop, using this guide http://www.macbreake...ion-######.html ("How To install Moutain Lion on your PC, same tuto here )I'm stuck at booting the installer (USB drive).I need to boot with "GraphicsEnabler=No" or else it stops as soon as the booting process starts, but it stops again to say "Still Waiting for root device".I've tried a lot of booting flags and nothing could solve the problem...

I would like to share my expericence about the sony vaio SVE1512Z1EB and mountain lion 10.8.2

1 I create my WIN 8 dvd really important indeed it cost a lost to make a recovery in my country.2 boot my machine with the "assit" button it allow a welcome screen giving you access to the bios3 Set the bios to legacy in the boot menu + enable external device boot4 use Gparted to remove all the partitions5 create bootable usb key by following this guide https://www.youtube....h?v=1sGICm2tXkU6 edit the org.chamelon.boot.plist on GraphicsEnabler change Yes to NO7 edit smbios.plist to macbook pro 9.28 add PXHCD.kext for the usb 3 in the E/E folder9 add RTGNIC v 2.0.6 for 10.7 from realtek ftp for the rtl 8111/8168b network card in the usb key when your mountain lion is up

Now here is where i ambluethooth worklan workcamera workneed external mouse and keyboard but workVideo card block on 1024x768 strangely the win id of the card is on the ATI6000.kext of mountaint lion (Dev 841)About this mac crash but i understand it is due to DSDT

I was going to try to create a DSDT (never did it before) until i found Clover and read that you do not need DSDT anymore sadly the downsize is that you need to be on UEFi wich is nice like this i can have win 8 and mountain lion.

So i found the article of Kogen Mantis Lenovo ThinkPad T420 with UEFI onlyCreate a usb key and copy is lenovo pack inside by comparing the key and his folder

I was not only able to boot in UEFI but have my mountain lion seen in the main menu and able to boot to a certain extend i am block after 5 displayed screens.

Now here is my question if someone can help

A is it real that we no longer need DSDT when we are booting in UEFI ?
